I have an old production server that runs Debian on a Q9550 CPU. I want to upgrade the server but I am on a very tight budget. I can't spend more than around $600. I can get a refurbished HP ProLiant DL380P G8 with 32GB RAM and 2x E5-2660 CPU for about that price.

Will the (dual) E5-2660 be a major improvement over the Q9550? If I look at both CPU's on cpubenchmark.net, the E5-2660 has a passmark score about 3x as high as the Q9550. But all other comparison sites say they are about the same speed.

The E5-2660 will be a improvement in CPU performance over the Q9550. It's a 4 year old newer chip and has 8 cores vs 4, and since your new system is a dual CPU you will have 16 cores, 4 times as many as before. On top of that, you also have Hyper-Threading which the Q9550 does not have.

According to CPU Mark rating found here:

Multi-threaded:

Q9550: 3,959

E5-2660: 11,279

Single-threaded:

Q9550: 1,196

E5-2660: 1,473

According to those numbers, you would at the very least see a 25% gain and could see nearly a 300% gain depending on your application's scaling.
